As illustrated in FIG. 2(a), an element 20 constituting a slide fastener SF1 includes an interlock portion 20H1 on one side in the horizontal direction H1 and a fastener-tape fixing portion 20H2, to which a fastener tape 10 is fixed, on the other side in the horizontal direction H1. The element 20 extends in vertical upward and downward directions V11 and V12 with respect to the horizontal direction H1. The element 20 includes an element-upper-leg portion 20V1 and an element-lower-leg portion 20V2. An upper portion of the element-upper-leg portion 20V1 that extends in the vertical upward direction V11 is bent into a hook shape. A lower portion of the element-lower-leg portion 20V2 that extends in the vertical downward direction V12 is bent into a hook shape.

In FIG. 4, in the case where the element-upper-leg portion 20V1 and the element-lower-leg portion 20V2 of each element 20 are both made of a nonelastic material, a power and/or signal input-output line L12 is formed in the following manner.

Moreover, the power supply input line L1 and/or the signal input-output line SL is/are connected to one of the opening-closing ends H1T in the horizontal direction H1 and the opening-closing ends V11T and V12T in the vertical upward and downward directions V11 and V12 or the input electrode section L1P to which the power supply input line L1 and/or the signal input-output line SL is/are connected is concurrently engaged with the opening-closing end. In addition, the power supply output line L2 extending to the powered device DK and/or the signal input-output line SL extending to the powered device DK is/are connected to another one of the remaining opening-closing ends or the output electrode section L2P to which the power supply output line L2 extending to the powered device DK and/or the signal input-output line SL extending to the powered device DK is/are connected is concurrently engaged with another one of the remaining opening-closing ends.

Alternatively, in the case where at least one of the element-upper-leg portion 20V1 and the element-lower-leg portion 20V2 of each element 20 is made of an elastic material, a power and/or signal input-output line L12 is formed in the following manner. By sliding the slider 30 along the elements 20 and 20 arranged so as to face each other, the elements 20 and 20 are interlocked to close the opening-closing ends H1T in the horizontal direction H1, which are opposing fastener tapes 10, and the input electrode section L1P or the output electrode section L2P is concurrently engaged, or subsequently joining in a push-in manner, with the top holding section 20V1R and the bottom holding section 20V2R to close the opening-closing ends V11T and V12T in the vertical upward and downward directions V11 and V12. Moreover, the power supply input line L1 and/or the signal input-output line SL is/are connected to one of the opening-closing ends H1T in the horizontal direction H1 and the opening-closing ends V11T and V12T in the vertical upward and downward directions V11 and V12 or the input electrode section L1P to which the power supply input line L1 and/or the signal input-output line SL is/are connected is concurrently engaged, or subsequently joined in a push-in manner, with the opening-closing end. In addition, the power supply output line L2 extending to the powered device DK and/or the signal input-output line SL extending to the powered device DK is/are connected to another one of the remaining opening-closing ends or the output electrode section L2P to which the power supply output line L2 extending to the powered device DK and/or the signal input-output line SL extending to the powered device DK is/are connected is concurrently engaged, or subsequently joined in a push-in manner, with another one of the remaining opening-closing ends.

In addition, as illustrated in FIG. 5(b) to FIG. 5(j), there are nine combination patterns for forming an input-output line L12 illustrated in FIG. 5(a), by connecting the power supply input line L1 and/or the signal input-output line SL to one of the opening-closing ends H1T in the horizontal direction H1 and the opening-closing ends V11T and V12T in the vertical upward and downward directions V11 and V12 or engaging the input electrode section L1P to which the power supply input line L1 and/or the signal input-output line SL is/are connected with the one of the opening-closing ends and by connecting the power supply output line L2 extending to the powered device DK and/or the signal input-output line SL extending to the powered device DK to another one of the remaining opening-closing ends or engaging the output electrode section L2P to which the power supply output line L2 extending to the powered device DK and/or the signal input-output line SL extending to the powered device DK is/are connected with another one of the remaining opening-closing ends.

Specifically, when the opening-closing end V11T in the vertical upward direction V11 is chosen as an input terminal from among the opening-closing ends H1T in the horizontal direction H1 and the opening-closing ends V11T and V12T in the vertical upward and downward directions V11 and V12, there are three variations of output terminal/terminals including: the above-described opening-closing end V12T in the vertical downward direction V12 (FIG. 5(b)); the opening-closing ends H1T in the horizontal direction H1 (FIG. 5(c)); and the opening-closing ends H1T in the horizontal direction H1 and the opening-closing end V12T in the vertical downward direction V12 (FIG. 5(d)). When, on the other hand, the opening-closing end V12T in the vertical downward direction V12 is chosen as an input terminal from among the opening-closing ends H1T in the horizontal direction H1 and the opening-closing ends V11T and V12T in the vertical upward and downward directions V11 and V12, there are three variations of output terminal/terminals including: the opening-closing end V11T in the vertical upward direction V11 (FIG. 5(e)); the opening-closing ends H1T in the horizontal direction H1 (FIG. 5(f)); and the opening-closing ends H1T in the horizontal direction H1 and the opening-closing end V11T in the vertical upward direction V11 (FIG. 5(g)). Moreover, when the opening-closing ends H1T in the horizontal direction H1 are chosen as input terminals from among the opening-closing ends H1T in the horizontal direction H1 and the opening-closing ends V11T and V12T in the vertical upward and downward directions V11 and V12, there are three variations of output terminal/terminals including: the opening-closing end V11T in the vertical upward direction V11 (FIG. 5(h)); the opening-closing end V12T in the vertical downward direction V12 (FIG. 5(i)); and the opening-closing end V11T in the vertical upward direction V11 and the opening-closing end V12T in the vertical downward direction V12 (FIG. 5(j)). Consequently, there are nine combinations of input terminal/terminals and output terminal/terminals in total.

The electrodes may be embedded in the fastener tapes 10 of the first and second elements 20 arranged so as to face each other, in the end portion of the element-upper-leg portion 20V1, inside the element-upper-leg portion 20V1, in the end portion of the element-lower-leg portion 20V2, and inside the element-lower-leg portion 20V2 in any of the nine combinations illustrated in FIG. 5(b) to FIG. 5(j).

In this drawing, in the case where each of multiple fastener units FU11, FU12, . . . is a fastener unit that includes an element-upper-leg portion 20V1 and an element-lower-leg portion 20V2 made of a nonelastic material, the multiple fastener units are formed into a stacked structure by, when the elements 20 and 20 of each fastener unit arranged so as to face one another are interlocked by sliding the slider 30 of the fastener unit along the elements 20 and 20 of the fastener unit, coupling the top holding section 20V1R of the first fastener unit FU11 to the bottom holding section 20V2R of the second fastener unit FU12 using the coupling electrode portion REP and then sequentially coupling the bottom holding section of each new fastener unit to the top holding section of the previous fastener unit using a coupling electrode portion.

In the case where the another one of the element-upper-leg portion 20V1 and the element-lower-leg portion 20V2 is made of an elastic material, the multiple fastener units are formed into a stacked structure by, when the elements 20 and 20 of each fastener unit arranged so as to face each other are interlocked by sliding the slider 30 of the fastener unit along the elements 20 and 20 of the fastener unit, coupling the top holding section 20V1R of the first fastener unit FU11 to the bottom holding section 20V2R of the second fastener unit FU12 using a coupling electrode portion REP or joining them together in a push-in manner when the holding sections are engaged with a coupling electrode portion REP, and then sequentially coupling the bottom holding section of each new fastener unit to the top holding section of the previous fastener unit when the holding sections are engaged with or subsequently joined in a push in manner with the coupling electrode portion.

Here, multiple fastener units may be formed into a stacked structure by coupling the bottom holding section 20V2R of the first fastener unit FU11 to the top holding section 20V1R of the second fastener unit FU12 when the holding sections are engaged with the coupling electrode portion REP or subsequently joined together in a push-in manner and then sequentially coupling the top holding section of each new fastener unit to the bottom holding section of the previous fastener unit when the holding sections are engaged with the coupling electrode portion or joined together in a push-in manner.

FIG. 7(1) is a schematic view of the opening-closing ends H1T1, H1T2, and H1T3 in the horizontal direction H1, which are closed by sliding the sliders 30 of three fastener units FU11, FU12, and FU13 formed into a stacked structure along the elements 20 and 20, and the opening-closing ends V11T and V12T in the vertical directions V11 and V12 of uppermost and lowermost fastener units in the case where multiple, for example, three fastener units FU1 are provided as slide fasteners SF1 according to the first embodiment and formed into a stacked structure by coupling the top holding section 20V1R of the first fastener unit FU11 to the bottom holding section 20V2R of the second fastener unit FU12 using the coupling electrode portion REP or subsequently joining them together in a push-in manner and then sequentially coupling the bottom holding section of each new fastener unit FU13 to the top holding section of the previous fastener unit FU12 using a coupling electrode portion or subsequently joining them together in a push-in manner. As illustrated in FIG. 7(2) to FIG. 7(76), there are 75 combination patterns that form an input-output line L12 by connecting the power supply input line L1 and/or the signal input-output line SL to one of the opening-closing ends H1T1, H1T2, and H1T3 in the horizontal direction H1 and the uppermost and lowermost opening-closing ends V11T and V12T in the vertical directions V11 and V11 or by engaging the input electrode section L1P to which the power supply input line L1 and/or the signal input-output line SL is/are connected with the one of the opening-closing ends, and by connecting the power supply output line L2 extending to the powered device DK and/or the signal input-output line SL extending to the powered device DK to another one of the remaining opening-closing ends or engaging the output electrode section L2P to which the power supply output line L2 extending to the powered device DK and/or the signal input-output line SL extending to the powered device DK is/are connected with another one of the remaining opening-closing ends. The combination patterns illustrated in FIG. 7(2) to FIG. 7(76) are examples when three fastener units are formed into a stacked structure as illustrated in FIG. 7(1). However, the number of combination patterns can be similarly calculated in the case where there are a different number of fastener units.

Specifically, when the uppermost opening-closing end V11T in the vertical direction V11 is chosen as an input terminal from among the opening-closing ends H1T1, H1T2, and H1T3 in the horizontal direction H1 and the uppermost and lowermost opening-closing ends V11T and V12T in the vertical directions V11 and V12, there are 15 variations of output terminal/terminals including: four ways in which one of the remaining four opening-closing ends is chosen as an output terminal (FIG. 7(2) to FIG. 7(5)); six ways in which any two of the opening-closing ends are chosen as output terminals in combination (FIG. 7(6) to FIG. 7(11)); four ways in which any three of the opening-closing ends are chosen as output terminals in combination (FIG. 7(12) to FIG. 7(15)); and one way in which the remaining four opening-closing ends are chosen as output terminals (FIG. 7(16)). Similarly, when the lowermost opening-closing end V12T in the vertical direction V12 is chosen as an input terminal, there are 15 variations of output terminal/terminals including: four ways in which one of the remaining four opening-closing ends is chosen as an output terminal (FIG. 7(17) to FIG. 7(20)); six ways in which any two of the opening-closing ends are chosen as output terminals in combination (FIG. 7(21) to FIG. 7(26)); four ways in which any three of the opening-closing ends are chosen as output terminals in combination (FIG. 7(27) to FIG. 7(30)); and one way in which the remaining four opening-closing ends are chosen as output terminals (FIG. 7(31)). When one of the opening-closing ends H1T1, H1T2, and H1T3 in the horizontal direction H1 is chosen as an input terminal, there are similarly 15 variations of output terminal/terminals (FIG. 7(32) to FIG. 7(46), FIG. 7(47) to FIG. 7(61), and FIG. 7(62) to FIG. 7(76)). Thus, there are 75 combinations of input terminal/terminals and output terminal/terminals in total.

In FIG. 10, in the case of a slide fastener in which an element leg portion 50V1 of each element 50 is made of a nonelastic material, a power and/or signal input-output line L12 is formed in the following manner. By sliding the slider 60 along the elements 50 and 50 arranged so as to face one another, the elements 50 and 50 are interlocked to close the opening-closing ends H5T in the horizontal direction H5, which are opposing fastener tapes 40. At the same time, the input electrode section L1P or the output electrode section L2P is concurrently engaged with the holding section 50V1R to close the opening-closing end V51T in the one vertical direction V51. Moreover, the power supply input line L1 and/or the signal input-output line SL is/are connected to one of the opening-closing ends H5T in the horizontal direction H5 and the opening-closing end V51T in the one vertical direction V51 or the input electrode section L1P to which the power supply input line L1 and/or the signal input-output line SL is/are connected is concurrently engaged with the opening-closing end. In addition, the power supply output line L2 extending to the powered device DK and/or the signal input-output line SL extending to the powered device DK is/are connected to another one of the remaining opening-closing ends or the output electrode section L2P to which the power supply output line L2 extending to the powered device DK and/or the signal input-output line SL extending to the powered device DK is/are connected is concurrently engaged with the another one of the remaining opening-closing ends.

Alternatively, in the case of a slide fastener in which the element leg portion 50V1 of each element 50 is made of an elastic material, a power and/or signal input-output line L12 is formed in the following manner. By sliding the slider 60 along the elements 50 and 50 arranged so as to face each other, the elements 50 and 50 are interlocked to close the opening-closing ends H5T in the horizontal direction H5, which are opposing fastener tapes 40, and the input electrode section L1P or the output electrode section L2P is concurrently engaged, or subsequently joined in a push-in manner, with the holding section 50V1R to close the opening-closing end V51T in the one vertical direction V51. Then, the power supply input line L1 and/or the signal input-output line SL is connected to one of the opening-closing ends H5T in the horizontal direction H5 and the opening-closing end in the one vertical directions V51 or the input electrode section L1P to which the power supply input line L1 and/or the signal input-output line SL is/are connected is concurrently engaged, or subsequently joined in a push-in manner, with the opening-closing end. In addition, the power supply output line L2 extending to the powered device DK and/or the signal input-output line SL extending to the powered device DK is/are connected to another one of the remaining opening-closing ends or the output electrode section L2P to which the power supply output line L2 extending to the powered device DK and/or the signal input-output line SL extending to the powered device DK is/are connected is concurrently engaged, or subsequently joined in a push-in manner, with the another one of the remaining opening-closing ends.

As illustrated in FIG. 11(b) and FIG. 11(c), there are two combination patterns for forming an input-output line L12 illustrated in FIG. 11(a) by connecting the power supply input line L1 and/or the signal input-output line SL to one of the opening-closing ends H5T in the horizontal direction H5 and the opening-closing end V51T in the vertical direction V51 or engaging the input electrode section L1P to which the power supply input line L1 and/or the signal input-output line SL is/are connected with the one of the opening-closing ends and by connecting the power supply output line L2 extending to the powered device DK and/or the signal input-output line SL extending to the powered device DK to another one of the remaining opening-closing ends or engaging the output electrode section L2P to which the power supply output line L2 extending to the powered device DK and/or the signal input-output line SL extending to the powered device DK is/are connected with the other one of the remaining opening-closing ends.

Specifically, when the opening-closing ends H5T in the horizontal direction H5 are chosen as input terminals from among the opening-closing ends H5T in the horizontal direction H5 and the opening-closing end V51T in the one vertical direction V51, the opening-closing end V51T in the one vertical direction V51 (FIG. 11(b)) is used as the output terminal. When the opening-closing end V51T in the one vertical direction V51 is chosen as an input terminal, the opening-closing ends H5T in the horizontal direction H5 (FIG. 11(c)) are used as the output terminals. Thus, there are two combinations of input terminal/terminals and output terminal/terminals.

FIG. 12 is a perspective view of the case where two slide fasteners SF4 according to the second embodiment, which are fastener units FU4, are formed into a stacked structure by coupling the holding sections 50V1R of the two fastener units FU41 and FU42 using a coupling electrode portion REP. In this drawing, when the two fastener units FU41 and FU42 are both fastener units having an element leg portion made of a nonelastic material, the two fastener units FU41 and FU42 are formed into a stacked structure by coupling the holding sections 50V1R of the two fastener units FU41 and FU42 together in the vertical direction using the coupling electrode portion REP when the opposing elements 50 of the two fastener units FU41 and FU42 are interlocked by sliding the sliders 60 of the two fastener units FU41 and FU42 along the elements 50 of the two fastener units FU41 and FU42.

In the case where at least the fastener unit FU41 of the two fastener units FU41 and FU42 is a fastener unit that has element leg portions made of an elastic material, if the fastener unit FU42 is a fastener unit that has element leg portions made of a nonelastic material, the two fastener units FU41 and FU42 are formed into a stacked structure by coupling the holding sections 50V1R of the fastener units together in the vertical direction using the coupling electrode portion REP when the opposing elements 50 of the fastener unit FU42 having element leg portions made of a nonelastic material are interlocked by sliding the slider 60 of the fastener unit FU42 along the elements 50 of the fastener unit. When the elements of the fastener unit FU41 having element leg portions made of an elastic material are subsequently interlocked, the holding sections 50V1R are concurrently coupled together using a coupling electrode portion REP or subsequently coupled together in a push-in manner in the vertical direction. In the case where the fastener unit FU42 is a fastener unit that has an element leg portion made of an elastic material, the two fastener units FU41 and FU42 are formed into a stacked structure by coupling the holding sections 50V1R of the fastener units having element leg portions made of an elastic material together using the coupling electrode portion REP when the opposing elements 50 of the two fastener units are interlocked by sliding the sliders of the two fastener units along the elements 50 of the two fastener units, or coupling the holding sections 50V1R together in a push-in manner in the vertical direction after the elements 50 have been interlocked.

FIG. 13(a) is a schematic view of the opening-closing ends H5T1 and H5T2 in the horizontal direction H5, which are closed by sliding each slider of two fastener units along the elements arranged so as to face each other, of the two fastener units in the case where two fastener units FU4 are provided as slide fasteners SF4 according to the second embodiment and formed into a stacked structure by coupling the holding sections 50V1R of the two fastener units together using a coupling electrode portion REP. As illustrated in FIG. 13(b) and FIG. 13(c), there are two combination patterns that form a power and/or signal input-output line L12 by connecting the power supply input line L1 and/or the signal input-output line SL to the opening-closing ends H5T1 in the horizontal direction H5 of one of the fastener units among the opening-closing ends in the horizontal direction H5 of the two fastener units formed into a stacked structure and by connecting the power supply input line L2 extending to the powered device DK and/or the signal input-output line SL extending to the powered device DK to the opening-closing ends H5T1 in the horizontal direction H5 of another one of the fastener units.

Specifically, when the opening-closing ends H5T1 in the horizontal direction H5 of a first one of the fastener units are chosen as input terminals from among the opening-closing ends H5T1 and H5T2 in the horizontal direction H5, the opening-closing ends H5T2 in the horizontal direction H5 of the second fastener unit (FIG. 13(b)) are used as output terminals. When the opening-closing ends H5T2 in the horizontal direction H5 of the second fastener unit are chosen as input terminals, the opening-closing ends H5T1 in the horizontal direction H5 of the first fastener unit (FIG. 13(c)) are used as output terminals. Thus, there are two combinations of input terminals and output terminals.

FIG. 14 to FIG. 17 are illustrations relating to a slide fastener according to a third embodiment of the present invention. As illustrated in FIG. 14(a), an element 80 constituting a slide fastener SF7 includes an interlock portion 80H1 on one side in the horizontal direction H8 and a fastener-tape fixing portion 80H2, to which a fastener tape 70 is fixed, on the other side in the horizontal direction H8. The element 80 also includes an element engagement piece 80V1 and an element-engagement-piece receiving piece 80V2. The element engagement piece 80V1 extends in the vertical upward and downward directions V81 and V82 with respect to the horizontal direction H8, and a portion of the element engagement piece 80V1 extended upward is formed into an arrow head shape. A portion of the element-engagement-piece receiving piece 80V2 extended downward is bent into a hook shape.

A (positive) power electrode 80KV11 is embedded in an arrow stick portion of the element engagement piece 80V1 and a (negative) power electrode 80KV12, an electrode 80KSAV1 for a signal A, and an electrode 80KSBV1 for a signal B are embedded in an arrow head portion. In addition, a (positive) power electrode 80KV21 is embedded in an end portion of the element-engagement-piece receiving piece 80V2 and a (negative) power electrode 80KV22, an electrode 80KSAV2 for a signal A, and an electrode 80KSBV2 for a signal B are embedded inside the element-engagement-piece receiving piece 80V2.

The (positive) power electrode 80KV11 embedded in the arrow stick portion of the element engagement piece 80V1, the (negative) power electrode 80KV12, the electrode 80KSAV1 for a signal A, and the electrode 80KSBV1 for a signal B embedded in the arrow head portion, the (positive) power electrode 80KV21 embedded in the end portion of the element-engagement-piece receiving piece 80V2, and the (negative) power electrode 80KV22, the electrode 80KSAV2 for a signal A, and the electrode 80KSBV2 for a signal B embedded inside the element-engagement-piece receiving piece 80V2 are electrically connected together inside the interlock portion 80H1 or along the surface of the interlock portion 80H1 and further respectively connected to a (positive) power electrode 70KV1, a (negative) power electrode 70KV2, an electrode 70KSAV1 for a signal A, and an electrode 70KSBV1 for a signal B, which are embedded in the fastener tape 70 fixed to the fastener-tape fixing portion 80H2.

As illustrated in FIG. 14(b), elements 80 of this type are arranged so as to face each other. By interlocking the interlock portions 80H1 and 80H1 of first and second elements 80 and 80 arranged so as to face each other, the element engagement pieces 80V1 and 80V1 of the elements 80 and 80 arranged so as to face each other form an element engagement portion 80V1R and the element-engagement-piece receiving pieces 80V2 and 80V2 of the elements 80 and 80 facing each other form an element-engagement-portion receiving portion 80V2R. The element engagement portion 80V1R has an arrow head shape having peak portions 80V1S at the tip. The element-engagement-portion receiving portion 80V2R has an arrow-head receivable shape in which portions of the element-engagement-piece receiving pieces 80V2 and 80V2 extended downward are formed into hook shapes 80V2G and 80V2G and the arrow-head-shaped element engagement portion 80V1R can be engaged with the element-engagement-portion receiving portion 80V2R.

As illustrated in FIG. 15, a slider 90 constituting the slide fastener SF7 includes a slider body 90T, which interlocks and unlocks the elements 80 by causing the elements 80 to pass therethrough, and a tab 90K, which moves the slider body 90T. The slider body 90T includes an upper-vertical-side case 90TU and a lower-vertical-side case 90TD. The slider body 90T also has horizontal slits 90TH, through which the fastener tapes 70 pass, between the upper-vertical-side case 90TU and the lower-vertical-side case 90TD.

The tab 90K includes an attachment portion 90KT, which is attached to the slider body 90T, and a tab portion 90KB. The attachment portion 90KT is engaged with a tab attachment portion 90TUK erectly provided on the upper-vertical-side case 90TU.

FIG. 16 is a perspective view of slide fasteners that form a power and/or signal input-output line in the case where multiple slide fasteners SF7 according to the third embodiment are used as fastener units FU7 and formed into a stacked structure by engaging the element engagement portion 80V1R of a first fastener unit FU71, which has been formed by interlocking the interlock portions 80H1 of the elements 80, with the element-engagement-portion receiving portion 80V2R of a second fastener unit FU72 and thus sequentially engaging the element engagement portion of the previous fastener unit with the element-engagement-portion receiving portion of each new fastener unit. In the third embodiment, one side portion of each element 80 functions as an element engagement portion 80V1R. Thus, no coupling electrode portion is needed to form the fastener units FU7 into a stacked structure.

In this drawing, in the case where one of multiple fastener units that includes element-engagement-piece receiving pieces 80V2 made of a nonelastic material is connected to the other fastener units in a stacked manner, the multiple fastener units are connected to each other in a stacked manner by, when the elements 80 and 80 of each fastener unit are interlocked by sliding the slider 90 of the fastener unit along the elements 80 and 80 of the fastener unit, engaging the engagement portion 80V1R of the first fastener unit FU71, which has been formed by interlocking the interlock portions 80H1, with the element-engagement-portion receiving portion 80V2R of the second fastener unit FU72 made of a nonelastic material and then sequentially engaging the element engagement portion 80V1R of the previous fastener unit with the element-engagement-portion receiving portion 80V2R of each new fastener unit. Then, a power and/or signal input-output line L12 is formed by connecting the power supply input line L1 and/or the signal input-output line SL to any one of the opening-closing ends H8T in the horizontal direction H8 of multiple fastener units and the opening-closing end V81T of the engagement-portion receiving portion of the lowermost fastener unit or engaging the input electrode section L1P to which the power supply input line L1 and/or the signal input-output line SL is/are connected with the one of the opening-closing ends and connecting the power supply output line L2 extending to the powered device DK and/or the signal input-output line SL extending to the powered device DK to another one of the remaining opening-closing ends or engaging the output electrode section L2P to which the power supply output line L2 extending to the powered device DK and/or the signal input-output line SL is connected with another one of the remaining opening-closing ends.

When a fastener unit including element-engagement-piece receiving pieces 80V2 made of an elastic material among multiple fastener units is connected to the other fastener units in a stacked manner, the multiple fastener units are connected together in a stacked manner by, when the elements 80 and 80 of the fastener units are interlocked by sliding the sliders 90 of the fastener units along the elements 80 and 80 of the fastener units, engaging the element engagement portions 80V1R of the first fastener unit FU71, which have been formed by interlocking the interlock portions 80H1, with the element-engagement-portion receiving portions 80V2R of the second fastener unit FU72 made of an elastic material and concurrently engaging, or subsequently joining in a push-in manner, the element engagement portions 80V1R of the previous fastener unit with the element-engagement-portion receiving portions 80V2R of each new fastener unit in a sequential manner. Then, a power and/or signal input-output line L12 is formed in the following manner. The power supply input line L1 and/or the signal input-output line SL is/are connected to one of the opening-closing ends H8T in the horizontal direction H8 of the multiple fastener units and the opening-closing end V81T of the engagement-portion receiving portion of the lowermost fastener unit or the input electrode section L1P to which the power supply input line L1 and/or the signal input-output line SL is/are connected is engaged, or joined in a push-in manner, with the opening-closing end. In addition, the power supply output line L2 extending to the powered device DK and/or the signal input-output line SL extending to the powered device DK is/are connected to another one of the remaining opening-closing ends or the output electrode section L2P to which the power supply output line L2 extending to the powered device DK and/or the signal input-output line SL extending to the powered device DK is/are connected is engaged, or joined in a push-in manner, with another one of the remaining opening-closing ends.

FIG. 17(a) is a schematic view of the opening-closing ends H8T1 and H8T2 in the horizontal direction H8 and the opening-closing end V8T of the engagement-portion receiving portion of the lowermost fastener unit, which are closed by sliding the sliders 90 of multiple fastener units along the elements 80 and 80, in the case where slide fasteners SF7 according to the third embodiment are provided as multiple fastener units FU7 and formed into a stacked structure by engaging the element engagement portions 80V1R of the first fastener unit FU71, which have been formed by interlocking the interlock portions 80H1 of the elements 80, with the element-engagement-portion receiving portions 80V2R of the second fastener unit FU72 and thus sequentially engaging the element engagement portions of the previous fastener unit with the element-engagement-portion receiving portions of each new fastener unit. In the case, for example, where two fastener units FU71 and FU72 are formed into a stacked structure, as illustrated in FIG. 17(b) to FIG. 17(j), there are nine combination patterns that form a power and/or signal input-output line L12 by connecting the power supply input line L1 and/or the signal input-output line SL to one of the opening-closing ends H8T1 and H8T2 in the horizontal direction H8 and the opening-closing end V8T of the engagement-portion receiving portions of the lowermost fastener unit or by engaging, or joining in a push-in manner, the input electrode section L1P to which the power supply input line L1 and/or the signal input-output line SL is/are connected with the one of the opening-closing ends and by connecting the power supply output line L2 extending to the powered device DK and/or the signal input-output line SL extending to the powered device DK to another one of the opening-closing ends or engaging, or joining in a push-in manner, the output electrode section L2P to which the power supply output line L2 extending to the powered device DK and/or the signal input-output line SL extending to the powered device DK is/are connected with another one of the opening-closing ends.

Specifically, when the opening-closing ends H8T1 in the horizontal direction are chosen as input terminals from among the opening-closing ends H8T1 and H8T2 in the horizontal direction and the opening-closing end V8T of the engagement-portion receiving portions of the lowermost fastener unit, there are three variations of output terminal/terminals including: two ways in which one of the remaining two opening-closing ends is used as an output terminal (FIG. 17(b) to FIG. 7(c)); and one way in which the remaining two opening-closing ends are used as output terminals in combination (FIG. 17(d)). Similarly, when the other opening-closing ends H8T2 in the horizontal direction are chosen as input terminals, there are three variations of output terminal/terminals including: two ways in which one of the remaining two opening-closing ends is used as an output terminal (FIG. 17(e) to FIG. 7(f)); and one way in which the remaining two opening-closing ends are used as output terminals in combination (FIG. 17(g)). In addition, when the opening-closing end V8T of the engagement-portion receiving portions of the lowermost fastener unit is chosen as an input terminal, there are three variations of output terminal/terminals including: two ways in which one of the remaining two opening-closing ends is used as an output terminal (FIG. 17(h) to FIG. 7(i)); and one way in which the remaining two opening-closing ends are used as output terminals in combination (FIG. 17(j)). Thus, there are nine combinations of input terminal/terminals and output terminal/terminals in total.

The electrodes may be embedded in the fastener tapes 70, the element engagement pieces 80V1, and the element-engagement-piece receiving pieces 80V2 in any of the nine combinations illustrated in FIG. 17(b) to FIG. 17(j). Alternatively, these electrodes may be embedded only in: the opposing fastener tapes; and element engagement pieces and element-engagement-piece receiving pieces that are connected together in a stacked manner or with which the input electrode section to which the power supply input line and/or the signal input-output line is/are connected and the output electrode section to which the power supply output line extending to the powered device and/or the signal input-output line extending to the powered device is/are connected are engaged, the opposing fastener tapes and the connected element engagement pieces and element-engagement-piece receiving pieces being opening-closing ends to which the power supply input line and/or the signal input-output line or the power supply output line extending to the powered device and/or the signal input-output line extending to the powered device to the powered device is/are connected, and the element engagement pieces and element-engagement-piece receiving pieces being included in the element engagement portions and the element-engagement-portion receiving portions of multiple fastener units formed into a stacked structure.

FIG. 18 to FIG. 22 are illustrations relating to an input electrode section, an output electrode section, and/or a coupling electrode portion, used in common in the embodiments described above. FIG. 18 illustrates an example of the input electrode section L1P. The input electrode section L1P includes an arrow-head-shaped electrode portion L1Py and a connecting portion L1Pc. Besides the (negative) power electrode, an electrode for a signal A and an electrode for a signal B, which transmit and receive various types of signals, are embedded in the electrode portion L1Py. The (positive) power electrodes are embedded on both sides of the connecting portion L1Pc and connected to the power supply unit PU (not illustrated) and the signal unit SU (not illustrated) disposed on an input side.

FIG. 19 illustrates an example of the output electrode section L2P. The output electrode section L2P includes an arrow-head-shaped electrode portion L2Py and a connecting portion L2Pc. Besides the (positive) power electrode and the (negative) power electrode, an electrode for a signal A and an electrode for a signal B, which transmit and receive various types of signals, are embedded in the electrode portion L2Py. The connecting portion L2Pc is connected to a lighting device DKL, serving as a powered device, disposed on an output side.

FIG. 20 to FIG. 22 illustrate examples of coupling electrode portions REP used in the first embodiment and the second embodiment for coupling multiple slide fasteners together to form a stacked structure. As illustrated in FIG. 20(a) for example, the coupling electrode portion REP includes arrow-head-shaped electrode portions REPy on both ends, which are connected together by a coupling portion REPc. FIG. 20(b) is an enlarged view of an arrow-head-shaped electrode portion REPy. FIG. 21 and FIG. 22 illustrate other examples of the coupling electrode portions. As illustrated in FIG. 21, an external input-output terminal REPT may be provided from a middle portion of the coupling portion REPc to enable multipoint connection to an input power supply unit, an output external powered device, and an input-output line. Furthermore, as illustrated in FIG. 22, electrode portions REPK may be additionally provided to the external input-output terminal REPT to enable multipoint connection to other slide fasteners.

Conceivable examples of the powered device DK include a lighting device DKL, a surveillance camera DKM, a microphone, a loudspeaker, a fire detector DKQ, a wireless LAN relay device DKC, an electric fan, a battery charger, a clock, a bar code reader, an infrared sensor (a human sensor), a security sensor (a glass breakage or intrusion alarming proximity sensor), an information display terminal (a digital signage), and a photovoltaic power generating panel. In the case where the powered device DK is a lighting device DKL, the lighting device DKL can broadcast or individually transmit control signals of lighting-on, lighting-off, blinking, and lighting-on-and-off patterns if identification information or an address is previously set to the lighting device DKL. Another powered device is also conceivable that only receives power supply from a slide fastener and receives control signals in a wireless manner.

Now, an example of use of a power and/or signal input-output line formed by a closing operation of a slide fastener according to the present invention is described in which the power and/or signal input-output line is/are stretchably provided to a ceiling in a building, a wall, an outer wall of a building, or a roadside tree, or radially from a standing pole in such a manner as to stretch a rope. FIG. 23(a) illustrates a specific example in which power and/or signal input-output lines formed by using slide fasteners according to each embodiment are stretchably provided to a ceiling of a building. FIG. 23(b) is a detailed illustration of a slide fastener to which lighting devices, serving as powered devices, are connected. FIG. 23(c) is a detailed illustration of a slide fastener to which a wireless LAN relay device, serving as a powered device, is connected. FIG. 24(a) illustrates a specific example in which power and/or signal input-output lines formed by using slide fasteners according to each embodiment are stretchably provided from a standing pole in such a manner as to suspend ropes in the air. FIG. 24(b) is a detailed illustration of a lighting device, serving as a powered device, connected to one power and/or signal input-output line.

FIG. 23(a) illustrates a specific example of power and/or signal input-output lines formed by using slide fasteners according to each embodiment in which the power and/or signal input-output lines are stretchably provided to a ceiling of a building. Multiple power supply lines L12P, L13P, and L14P formed by slide fasteners SF1, SF4, and SF7 according to each embodiment are stretched along a ceiling of a building. An end of the power supply line L12P is connected to a power supply unit PU (not illustrated). In the case where the slide fasteners SF1 according to the first embodiment or the slide fasteners SF4 according to the second embodiment are used, the power supply lines L13P and L14P are coupled together via coupling lines L15P, which are branched to both sides from a fastener unit FU1 of multiple fastener units formed into a stacked structure using a coupling electrode portion REP. Power is supplied to the power supply lines L13P and L14P through the power supply line L12P, thereby activating the powered devices DK. In the case where the slide fasteners SF7 according to the third embodiment are used, multiple fastener units can be formed into a stacked structure without using coupling electrode portions. Thus, the power supply lines L13P and L14P are coupled together via coupling lines L15P, which are branched to both sides from the fastener unit FU1 among multiple fastener units formed into a stacked structure. Power is supplied to the power supply lines L13P and L14P through the power supply line L12P, thereby activating the powered devices DK. As examples of the powered devices DK, lighting devices DKL1 and DKL2 and a fire alarm DKQ are connected to the power supply line L12P, a wireless LAN relay device DKC and a lighting device DKL3 are connected to the power supply line L13P, and a surveillance camera DKM and a lighting device DKL4 are connected to the power supply line L14P.

FIG. 23(b) is a detailed illustration of a slide fastener SF to which lighting devices DKL, serving as powered devices DK, are connected. The slide fastener SF1 according to the first embodiment is used as the slide fastener. FIG. 23(c) is a detailed illustration of a slide fastener SF to which a wireless LAN relay device DKC, serving as a powered device DK, is connected. The slide fastener SF4 according to the second embodiment is used as the slide fastener.

FIG. 24(a) illustrates a specific example in which power and/or signal input-output lines formed by using slide fasteners according to each embodiment are stretchably provided radially from a standing pole in such a manner as to stretch ropes. A power and/or signal input-output line L12 formed by a slide fastener SF is installed on a pole CW standing in the center. The end of the power and/or signal input-output line L12 is connected to a power supply unit PU and/or a signal unit SU. Power and/or signal input-output lines L12 are radially stretched from the pole CW standing in the center to multiple poles CWn installed around the center pole CW in such a manner as to stretch ropes. Thus, power and/or signals is/are supplied by a closing operation of the slide fasteners SF.

FIG. 24(b) is a detailed illustration of a lighting device DKL, serving as a powered device DK, connected to the power and/or signal input-output line L12. Not only power from the power unit PU, but also control signals of lighting-on, lighting-off, blinking, and lighting-on-and-off patterns are concurrently or individually transmittable from the signal unit SU to the lighting device DKL if identification information or an address has previously been set to the lighting device DKL. Another powered device is also conceivable that only receives power supply from a slide fastener and receives control signals in a wireless manner.

As is clear from the above description, according to a slide fastener of the present invention, an input-output line that activates a powered device can be formed by a closing operation of a slide fastener including uniquely shaped elements, the input-output line being stretchable along a ceiling in a building, a wall, an outer wall of a building, or a roadside tree, or radially from a standing pole in such a manner as to stretch a rope. Thus, places at which the powered device is installed are not limited and the power device that has been installed may be moved to and used at another place.
